AP Chemistry Calculator Permissibility Checker
An interactive tool to check if your calculator meets the AP Chemistry exam rules.
Check Your Calculator’s Features
Does it have functions like log, sin, cos, etc.? This is highly recommended.
Can it plot graphs of functions? Most graphing calculators are allowed.
Can it perform symbolic algebra (e.g., solve for x)? This is a critical feature to check.
Does it have a keyboard like a computer (e.g., TI-92 Plus)?
Can it connect to the internet, Wi-Fi, or other devices via infrared?
What is the AP Chemistry Calculator Policy?
The question of whether you can use a calculator on the AP Chemistry exam is a critical one for test preparation. The simple answer is **yes, calculators are not only allowed but also highly recommended**. For the AP Chemistry exam, students are permitted to use a scientific or a graphing calculator on both the multiple-choice and the free-response sections. [3] This policy recognizes that the exam focuses on chemical principles and problem-solving skills rather than on manual arithmetic calculations. However, not all calculators are created equal in the eyes of the College Board. There are strict rules about the types of features a calculator can and cannot have.
The primary goal of the policy is to ensure fairness and prevent any student from having an unfair advantage through technology. This means that devices with capabilities that go beyond calculation, such as those with internet access or communication features, are strictly forbidden. Understanding whether your specific model is compliant is essential for a smooth and penalty-free exam day. [4]
Official College Board Calculator Rules
The College Board outlines specific guidelines for calculator usage. While the full policy has nuances, the core rules can be summarized in a table. It is crucial to know which features are permitted and which are strictly prohibited. The memory on your calculator does not need to be cleared before or after the exam. [2]
| Feature / Capability | Permissibility Status | Explanation |
|---|---|---|
| Scientific Functions (log, ln, trig) | Permitted | These are considered standard and necessary for the calculations on the exam. |
| Graphing Capabilities | Permitted | Most standard graphing calculators (like the TI-84 series) are allowed. |
| QWERTY (Typewriter-style) Keyboard | Prohibited | Calculators with keyboards like a computer are not allowed. [9] |
| Internet or Wireless Communication | Prohibited | Any device that can communicate with other devices or the internet is banned. [4] |
| Stylus or Pen Input | Prohibited | Calculators requiring a stylus (e.g., Casio FX-CG500) are only allowed if used without the stylus. [2] |
| Computer Algebra System (CAS) | Conditional | This is the most confusing rule. Some CAS calculators (like the TI-Nspire CX II CAS) are permitted because their keypad is alphabetical, not QWERTY. Always check the official approved list. |
| Makes Noise or Requires Outlet | Prohibited | Calculators must be silent and battery-operated. |

Practical Examples of Allowed Calculators
To make the rules more concrete, here are examples of calculators that are generally allowed for the AP Chemistry exam:
- Texas Instruments TI-84 Plus CE: A widely used and fully compliant graphing calculator.
- Texas Instruments TI-30XIIS: A popular and affordable scientific calculator that meets all requirements.
- Casio fx-9750GII: A permitted graphing calculator model.
- Texas Instruments TI-Nspire CX II (non-CAS and CAS versions): Both are generally allowed because their keyboards are not QWERTY. The CAS functionality provides a significant advantage in solving equations. [1]
A calculator that would be **prohibited** is the TI-92 Plus, as it features a QWERTY keyboard.
How to Use This AP Chemistry Calculator Checker
This page’s interactive tool is designed to help you quickly determine if your calculator is likely to be permitted. Follow these simple steps:
- Review your calculator’s features. Check the original packaging, the manufacturer’s website, or the device itself.
- Select the checkboxes at the top of the page that match your calculator’s capabilities. Be honest about features like CAS functionality and keyboard style.
- Click the “Check Permissibility” button.
- The result will appear below, indicating whether your calculator is likely ‘Permitted’ or ‘Prohibited’ based on the combination of features you selected, along with an explanation of the reasoning.

Key Factors That Affect Calculator Permissibility
When you want to determine if you can use a calculator on the AP Chemistry exam, several key factors come into play. Understanding these will help you choose the right tool.
- Keyboard Layout: This is a non-negotiable rule. Any calculator with a QWERTY keyboard is banned.
- Communication Technology: Infrared ports, Wi-Fi, or Bluetooth capabilities are strictly forbidden.
- Power Source: The calculator must be battery-powered. You cannot plug it into an outlet.
- CAS Functionality: This is the most ambiguous rule. While CAS itself is not explicitly banned, the devices that have it often have other banned features. However, models like the TI-Nspire CAS are on the approved list, giving users a distinct advantage. [9]
- Physical Size and Form: Laptops, tablets, and phones are not calculators and cannot be used.
- Noise/Output: Calculators that make noise or print to a paper tape are not permitted.

Frequently Asked Questions (FAQ)
1. Can you use a calculator on both sections of the AP Chemistry exam?
Yes, a scientific or graphing calculator is recommended for both the multiple-choice and the free-response sections of the exam. [7]
2. Do I have to clear my calculator’s memory?
No, the College Board does not require you to clear your calculator’s memory before or after the AP Chemistry exam. [2]
3. Can I bring two calculators?
Yes, you are permitted to bring up to two approved calculators to the exam in case one malfunctions. [8]
4. Is the TI-Nspire CX II CAS allowed?
Yes, as of the latest policies, the TI-Nspire CX II CAS is allowed because its keyboard is alphabetical (ABCD) and not QWERTY. This provides a significant advantage for solving equations. [9]
5. What happens if I bring a prohibited calculator?
If a proctor identifies your calculator as prohibited, you will not be allowed to use it. In the worst-case scenario, attempting to use a banned device could lead to the cancellation of your exam score.
6. Can I use my phone as a calculator?
No, phones, smartwatches, and any other communication devices are strictly prohibited. [4]
7. Are scientific calculators enough, or do I need a graphing one?
A good scientific calculator (like the TI-30XIIS) is completely sufficient for all calculations on the exam. A graphing calculator offers no major advantage for the types of questions asked in AP Chemistry, unlike in AP Calculus.
8. What if I forget my calculator?
You may have to take the exam without one, which is a significant disadvantage. Some schools may have loaner calculators, but you should not count on this. You can sign a release form to take the exam without a calculator. [7]
